Abstract

We study deformation rings of n-dimensional mod l representations ρ of the arithmetic fundamental group π1(X) where X is a geometrically irreducible, smooth curve over a finite field k of characteristic p (6 = l). We are able to show in many cases that the resulting rings are finite flat over Zl. The proof principally uses a lifting result of the authors in… (More)
